Surely the J2 LPL ops is to stifle any RYR / EZY expansion aspirations?. Back in the day Britannia /Thomson had a reasonable IT programme ex Liverpool serviced by W pattern Manchester based aircraft. TUI have certainly lost their way.
On the other topic, my gut instinct is that MAG are happy to aspire to greater bucket and spade flights as they are easier targets for all the duty free, bars, restaurants and car park ancillary revenue. Hence the lack of interest in repairs to infrastructure (fix walkways by taking them out) bus station falling into disrepair as are other parts of the airport, part of the Charlie Cornish tight reign on spending. T2 TP scaled back in facilities, freight discouraged, lots of things appear to have moved into the too difficult box, I guess ambitious route development is parked there too. They are relying on growth from Ryanair,J2 and easyjet IMHO.
